 This section was written after a contribution by Alexander Belchenko on
 the IPython user list.
 
-.. The section below needs to be updated for the new config system.

-.. Effective logging
-   -----------------
-
-.. A very useful suggestion sent in by Robert Kern follows:
-
-.. I recently happened on a nifty way to keep tidy per-project log files. I
-   made a profile for my project (which is called "parkfield")::
-
-    include ipythonrc
-
-    # cancel earlier logfile invocation:
-
-    logfile ''
-
-    execute import time
-
-    execute __cmd = '/Users/kern/research/logfiles/parkfield-%s.log rotate'
-
-    execute __IP.magic_logstart(__cmd % time.strftime('%Y-%m-%d'))
-
-.. I also added a shell alias for convenience::
-
-    alias parkfield="ipython --pylab profile=parkfield" 
-
-.. Now I have a nice little directory with everything I ever type in,
-   organized by project and date.
-
-.. warning::
-   
-   This example uses the outdated ipythonrc-style configuration files, which no
-   longer work as of IPython 0.11
